He turned to social media again on Christmas to post a picture of Lillie in a pink Christmas onesie with red cuffs, dotted with snowmen and Santa Clauses. She's lying on her back with her little eyes squeezed tightly closed, with her tiny right fist up under her chin as if she might be contemplating something.

Haywood and Lady A bandmate Hillary Scott both announced they were expecting in August, with Scott later revealing that she's expecting twin girls in February. That will bring the Lady Antebellum baby total to six, including Scott's daughter Eisele and Charles Kelly's son Ward, born in February 2016.

Haywood admitted in August that the prospect of having of having a little girl was both thrilling and a little bit nerve-wracking.

"Yes we are beyond excited for a baby girl this Dec!!! Really can't believe it," he wrote. "We feel very blessed, partly terrified, and I've already cried twice and the baby is not even here yet."
